Mayor Muriel Bowser is weighing in after the FBI executed a raid at the home of D.C. Councilmember Jack Evans on Friday morning.
Federal authorities have not elaborated on what brought them to the home of the embattled council member on Friday, saying only that they were conducting a "court-ordered law-enforcement activity" there.
Evans has been reprimanded for alleged "influence peddling" by the D.C. Council.
"Clearly all of the revelations of this week have been disturbing. They're very serious allegations. And it's clear that the Federal investigation is proceeding," Bowser said.
The FBI raid arrives one day after FOX 5 obtained a letter signed by Evans indicating that he would resign both from his WMATA board chairman post, and from his place on the board altogether on June 27.
WMATA board ethics officials investigated Evans and found at least one violation.
Maryland Gov. Larry Hogan had already been calling for Evans to resign from the WMATA board.
The mayor stopped short of calling for Evans to resign from the D.C. Council but acknowledged that he faces serious allegations.
